SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 769,374, dated Sep be6, 1904.

i Application filed March 10, 1904. Serial No. 197,508. (No model'.)

. To all whom it may concern.-

Be it known that I, SrARKs M. BERRY, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented anew and useful Sash-Fastener, of which thefollowing is a specification.

The object of this invention is to provide a sash-fastener which when inproper place on the sash and locked or unlocked and with the sash eitherraised or lowered will be almost entirely concealed from view, thegeneral The accompanying drawings illustrate the invention, andreferring thereto Figure 1 is a perspective of a portion of a windowwith the invention applied to the sash. Fig. 2 is a plan view of theinvention, showing part of the sash. Fig. 3 is a horizontal sectiontaken through the center of the sleeve, showing part of the sash. Fig. 4is a'plan view of the lockframe with the top plate broken away. Fig. 5is a rear elevation of the device. Fig. 6 is a perspectiveof'the'face-plate. Fig. 7 is aperspective of the locking-bolt. Fig. 8 isafront elevation of the bolt-frame.

Referring to the drawings, 1 designates the upper sash, and 2 designatesthe lower sash. To the uppersash 1 is screwed aface-plate 3, having anorifice 4. The plate is beveled, as at 5, forming an inclinedbearing-face which gradually merges with the wall of the orifice 4. Abolt-frame, which consists of a top plate '6 and a front plate 7 atright angles thereto,

is screwed to the lower sash 2, and the top plate 6 is provided with anelongated slot 8, which merges with an offset slot 9, affordingstop-walls 10 and 11, and a guard 12. The front plate 7 has an orifice13, similar in outline to the orifice 4. A sleeve 14 projects inwardlyfrom the face-plate 7 underneath the top plate 6, With its axissubstantially parallel withthe top plate. The sleeve in its upper wallisslotted longitudinally at 15 and is provided with asegmental slot 16.Arevoluble and slidable locking-bolt 17 lies within the sleeve 14 andhas a neck 18,.whichcarries a head 19. A finger-piece 20 projectsradially from the bolt 17 and lies within the slot 8, and by-rocking thefinger-piece through the slot 8 the bolt 17 may be turned.

The finger-piece 20 is preferably formed integral with the bolt, whichnecessitates making the slots 9 and 15 open at the rear andsubstantially in the same plane with the axis of the bolt, so that thefinger-piece can pass into the slot 8 as the bolt is inserted into thesleeve 14. The stop 12 stands across the portion of the slot 9 in linewith the end of slot 8,.and will thereby.engagewith the fingerpiece 20and prevent its passage out of the slot 9 until it has been rockedbeyond the stop.

The head 19 of the bolt isrectilinear in outline and is adapted to enterthe plate 3 through the slot 4, and by turning the bolt the head sweepsaround and grips theback of the plat-e 3. The inner face of the head 19is beveled, as shown, so that as the finger piece 20 is turned towardthe stop-wall 10 the inclined face of the head 19 rides upon the beveledface 5,

and the resulting action is to draw the upper and lower sash toward eachother and squeeze the plates 3 and 7 tightly together. By constructingthe-bolt and frame in this manner it is necessary to recess the sash forthe boltframe and the face-plate and also for the sleeve and the head ofthe bolt, so that the front plate and the face-plate will each be flushwith its sash, and thus permit of the two sash making a close joint whenthe window is closed.

The sash may be unlocked by turning the finger-piece 20 against thestop-wall 11, which rocks the locking-bolt, so that the head 19 mayreadily pass through the orifice 4.in plate 3. The finger-piece 20 isthen pulled into the slot 9 until it strikes the guard 12, which slidesthe locking-bolt along the sleeve 14 and withdraws the neck and head ofthe lockingbolt from the plate 3. i

It will be noted that the screws which fasten either member of thedevice to the sash pass transversely'into the sash, so that the holdingpower of the screws is very much greater than the holding power ofscrews as employed in securing the ordinary form of sash-fastener to thesash, as in the latter when sufficient force is applied to raise orlower the sash the screws may be forced lengthwise out of the wood, thewood tearing out along the screwthreads, while in the present device itis impossible to force a sash open, as the pressure sustained by thescrew is a lateral pressure and the only way to force the attachmentfree from the sash would be by shearing the screws, which could not beaccomplished without injuring the sash itself in consequence of thesevere strain necessary to shear the screws.

When the device is unlocked and the fingerpiece 20 lies within the slot9, the angular disposition of the finger-piece 20 causes it to abutagainst a shoulder 21, and this shoulder serves to prevent theaccidental outward shifting of the locking-bolt when unlocked, making itnecessary in order to lock the device to slightly raise the finger-piece20, so that it clears the shoulder 21, before the locking-bolt may beslid outward. Sufiicient clearance is provided between the finger-piece20 and a shoulder 22 to allow of the necessary slight upward raising ofthe finger-piece 20 to clear the shoulder 21.

It is obvious that when the device is applied to the sash the only thingprojecting from the sash at any point is the small tip of thefingerpieee 20, and this is of such insignificant proportions that itdoes not mar the appearance of the sash. 7

It is obvious that it is impossible to force a window when locked by thepresent device without tearing the sash or breaking the glass, and thisfeature, together with the unobtrusiveness of the device when applied,is considered of particular importance and value.

What I claim is 1. A sash-lock comprising a slotted boltframe, a sleevethereon below the top and having its axis substantially paralleltherewith, a bolt revoluble and slidable in the sleeve,

a finger-piece on the bolt extending through the slot in the frame, aplate having an orilice for receiving the bolt, and means on the boltfor engaging the plate.

2. A sash-lock comprising a slotted boltframe, a sleeve thereon belowthe top and having a longitudinal and segmental slot, a bolt revolubleand slidable in the sleeve, a finger-piece projecting from the boltthrough the slotted sleeve and through the slot in the frame, a head onthe bolt, and a plate having an opening for receiving the head of thebolt.

3. A sash-lock comprising a bolt-frame havinga top plate and a sideplate, the top plate having an elongated slot, and having an oilset slotmerging therewith, a guard at the mouth of the offset slot, a sleeve onthe frame below the top plate, a bolt revoluble and slidable in thesleeve and a linger on the bolt projecting through the slot.

4. A sash-fastener comprising a bolt-frame having a top plate and a sideplate, the top plate having an elongated slot and an oll'set slotmerging therewith and the side plate having screw-holes, a slottedsleeve on the frame below the top plate, the slot in the sleeve and theoffset slot in the top plate, each being open at the rear and the offsetslot being provided with a stop at its mouth, a bolt rcvolu ble andslidable in the sleeve, a neck and head on the bolt, a linger-piece onthe bolt projecting through the slot in the sleeve and through the slotin the top plate, and a faceplate having a slot for receiving the headof the bolt.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, at Los Angeles, in the county ofLos Angeles and State of California, this tth day of March, 1904.
